Perhaps I'd prefer to say somehow more precise (feel free to improve my
sentence):

The Blend Algebra/Blend Program plugins provide the advanced feature of
combining and modifying color pixels and transparencies of several tracks
according to a mathematic algorithm written entirely by the user in the form
of compact and simple piece of code. Such user defined algorithms (blend
functions) are compiled, dynamically linked and immediately executed inside
Cinelerra on the fly without the need to restart application, reload
project, reattach plugins etc.
